Abstract: PURPOSE:To make it possible to easily confirm the measuring position of an electron beam by scanning a wider area than the spot diameter of a electron beam on the surface of a sample by means of the electron beam and deciding the radiation position of electron beam based on the image of the obtained sample. CONSTITUTION:First, the position of a sample is fixed so that an enlarged image of a portion desired to be analyzed maybe formed on a fluorescent screen 7, and an electron beam is focused to a spot diameter with which the analysis is to be performed thereafter. At this juncture, through the portion of the sample on which the electron beam is radiated can not be confirmed because of extremely small spot diameter the enlarged image of the sample can be observed on the fluorescent plate 7 by changing the setting of an attenuator 9 and applying the output from an oscillator 8 to a deflection coil 3 thus enabling radiation over a wider area than the spot diameter. The radiation center of the electron beam is shifted by means of a spot position adjusting potentiometer 10 while confirming the portion desired to be enlarged through the enlarged image of the sample. In this way, the part of a sample on which the electron beam is radiated can be easily confirmed.

Filed: 1990-11-21
Abstract: PURPOSE:To enhance the safety and economy by enlarging the wall thickness to outside dia. ratio of a fuel rod covering tube with a hybrid oxide fuel rod (MOX fuel rod) including Pu, compared with a U fuel rod. CONSTITUTION:In a fuel assembly consisting of a MOX fuel rod 1, U fuel rod 2, and gadolinia-added U fuel rod 3, the MOX fuel rod 1 emits much fissile gas, and the inner pressure of a MOX fuel rod covering tube 6 maximizes in the latest period of combustion accordingly. Therefore, the ratio of the wall thickness tp of the covering tube 6 to its outside dia. Dp is made greater than the corresponding ratio tu/Du of the fuel rod 3, and the mechanical strength of the covering tube 6 is made stronger than the fuel rod 2 and the gadolinia- added U fuel rod 3. Thus the soundness of the covering tube 6 can be well maintained even in the latest period of combustion when the tube inner pressure heightens. Also a high grade of combustion can be achieved to ensure enhancement of the economy.

Title: Semiconductor memory device
Inventor: WATABE KIYOTO
IPC: G11C11/41
Filed: 1986-12-27
Abstract: PURPOSE:To simplify the manufacturing process by connecting transistors between the drain and the gate where flip flops included in a memory cell are cross-connected. CONSTITUTION:In the store state, a word line W is set to a 'L'-level, so transistors Q7, Q8 become nonconducting. And, since the threshold voltages of the transistors Q7, Q8 are set low, a low drain current flows through the transistor Q7(Q8) and that current value becomes sufficiently larger than each gate leakage current. In the read state, the word line W is set to a 'H'-level, so the transistors Q7, Q8 come into an ON state and the resistances thereof remarkably decrease. In the write state, since the word line W is set to the 'H'-level, the resistances of the transistors Q7, Q8 has remarkably decreased. Since the transistors Q7, Q8 have thus been inserted between the drain and the gate where flip flops are cross-connected, a device having a high soft error resistance can easily be obtained.
